Round or oval tables of a known kind which can be enlarged on all sidesare of a very complicated construction so that they have not beengenerally adopted. This applies more particularly to known tables of thekind in which hingedtogether segment-shaped enlarging parts areprovided, which when not in use are folded one over the other to form apile and are housed in the space below the table top.v For enabling thesegment-shaped enlarging pieces to be spread out it has been proposed todivide the top part of the frame into sections and to' make thesesections capable of being hinged downwards. The subdivision of the toppart of the frame into a number of parts and the fact that the saidparts of the frame must be unlocked and locked again both renders themanipulation of the table dimcult and renders the structure insecure.For this reason in the known tables each section of the top part of theframe is provided with a hinged sub-section, which serves as asupporting rail i'or the enlarging pieces. Furthermore as the xed tabletop covers the enlarging mechanism the difliculties in operating thetable are considerably increased.

The same applies to table constructionsy of the above kind in which boththe table top and the top part of the frame are xed. In suchconstructions complicated bow-shaped arrangements are provided, whichenable the enlarging segments to be passed round the upper part of theframe. Y

All these disadvantages are overcome by the present invention throughthe table top being :arranged to move upwards for enabling the enlargingsegments to be removed from the space within the top part of the frameto the outside and vice versa. The top part of the frame itseli'llremains stationary and can provide very elllcient support for theenlarging segments.

. The invention can be embodied in various constructional forms. Thusthe table top maybe composed of two halves hinged together and the pileof segments belonging to one half of the jtable top may be hinged to thetop part of the frame in such a manner that on the half of the table topbeing hinged up, the pile of segments can be hinged out of theinoperative to the operative position and vice versa. This arrangement lhas the further advantage that the hinging out'- wards of the enlargingelements may take place as it were automatically. For this it is onlynecessary to provide between the half of the table top and the pile ofsegments belonging to it a exible. pivotal or other connection, whichmakes the movement'of the half table top and the pile of segmentsinterdependent.

The invention is clearly illustrated in the accompanying drawing, inwhich:

Fig. 1 is a plan view of a table with a twopart table top,

Fig. 2 is aside view of the upper part of the table according to Fig. 1.partly in section.

In the table according to Figs. 1 and 2, the table top is divided intotwo halves;` a and b which are hinged together. The enlarging parts arein the form of segments c, three segments being in each case combined toform a unit, so that one group of segments is composed of the segmentsc1, c, c and the other group of the segments C4, c, c". The segments ofa group are connected together by hinges d and e so that in each casethree segments can be superposed to form a pile (Fig. 2). Each pile ofsegments is supported by two supporting arms f which are connected tothe top part h of the table frame by a hinge joint g. In this connectionit is to be noted that the inner edge of the frame h is constructed instepped formation the hinges g being connected to the free edges of theintermediate step so that when the arms f are in inoperative positionthey are supported on, the lower step and when in an operative positionare supported on the intermediate step passing through a groove in theupper edge of the frame. This arrangement permits the sections a and bto also engage the upper edge of the frame when the arms are arranged inan opposite position. Fig. 2 shows how the pile of segments is broughtfrom the. inoperative into the operative position and vice versa. Thetable top half a is raised. By means of a exible connection i, forinstance a piece of girthing, the pile of segments is also raised. Onlya small amount of pressure is then required for hinging over the pile ofsegments to the outside, the half a of the table top returning into itsnormal position. The pile of segments is then spread out, so that thesegments rest closely against the periphery of the half a of the tabletop as shown in full lines in Fig. 1. The broken lines in Fig. 1indicate how the pile of segments is housed inthe space within the toppart of the frame. A bar :i is preferably provided in the top part ofthe table frame, for supporting the pile of segments. Suitable lockingdevices may of course be provided between the two groups of segments forobtaining a closed rigid enlarged Dart.

It is believed in view of the foregoing that a further detaileddescription of the operation of the invention is unnecessary. Likewiseit is believed that the advantages of the invention will be readilyapparent.

What I claim is:

1. A table including an open supporting frame, a top on the frameincluding a pair of sections hinged with respect to each other and eachadapted for vertical swinging movement relative 2. A table as claimed inclaim 1, wherein lex.

ible connection means are providedbetween each top section and theoutermost enlarging me1riber onthe adjacent supporting arm for thepurpose of causing an upward swinging motion and partial raising of saidarm With the pile of enlarging members thereon upon the raising of eachtop section.

3. A table as claimed in claim 1, wherein the inner edge of the frame atthe point Where the arms are pivoted are constructed in steppedformation, the lower and intermediate steps acting to support the armswhen they are respectively in an inoperative and operative position.

4. A table as claimed in claim 1, wherein supporting bars are arrangedacross the table frame near the lower edge for supporting the topenlarging members when the latter are in inoperative position to ensureof their remaining in pile formation when in such position.
